The Rose of Jericho, often called the “resurrection plant,” is a unique desert plant known for its remarkable ability to curl into a seemingly lifeless ball when dry and then unfurl and turn green when rehydrated. This intriguing plant, scientifically known as Selaginella lepidophylla, can be a captivating addition to any home. While its “resurrection” is fascinating, mold growth is a common concern. Addressing mold on your Rose of Jericho ensures its continued health and longevity.
Identifying Mold on Rose of Jericho
Recognizing mold on your Rose of Jericho involves observing specific visual cues. Common molds typically appear as fuzzy patches with colors ranging from white, gray, black, or green. These patches can develop on the plant’s fronds, stems, or even in the water it sits in. A musty or earthy odor from the plant or its water can also signal mold.
It is important to differentiate mold from mineral deposits. Mineral deposits, often from hard water, may look like white, powdery residue but are dry to the touch and do not spread. Mold, by contrast, feels wet or slimy and expands over time. If you observe dark, wilted, or discolored areas on the plant accompanied by a fuzzy texture, it is likely mold.
Understanding Mold Causes
Mold thrives in environments that provide consistent moisture, warmth, and limited air circulation. For the Rose of Jericho, a plant naturally adapted to arid conditions, these factors quickly become problematic. Prolonged submersion in water without adequate drying periods is a primary cause of mold growth. Stagnant water, particularly if not changed regularly, creates an ideal breeding ground for mold spores.
Poor air circulation around the plant prevents moisture from evaporating, leading to a humid microclimate that encourages fungal development. This continuous wetness, especially when combined with insufficient ventilation, provides ideal conditions for mold spores to germinate and colonize. The Rose of Jericho’s natural cycle involves periods of complete dryness, and disrupting this cycle by keeping it constantly wet makes it highly susceptible to mold.
Removing Mold From Your Plant
Safely removing mold from your Rose of Jericho requires a gentle approach. Begin by wearing gloves. Carefully remove the plant from its water source and place it on a clean surface. Gently rinse the plant under cool, running water to dislodge loose mold and debris.
For stubborn mold patches, use a soft brush, such as a soft-bristled toothbrush, or a soft cloth to carefully scrub the affected areas. A diluted natural antifungal solution can also be effective. A mixture of one teaspoon of baking soda per quart of water can be sprayed onto the moldy areas until thoroughly wet. Alternatively, a diluted hydrogen peroxide solution (e.g., one part 3% hydrogen peroxide to nine parts water) can be used. After applying any solution, rinse the plant again with clean water. Thoroughly dry the plant in a well-ventilated area, allowing it to return to its dormant state before rehydrating.
Preventing Future Mold Growth
Preventing mold on your Rose of Jericho involves replicating its natural desert conditions and maintaining proper care routines. Establish a consistent hydration cycle that includes periods of complete dryness. Allow the plant to dry out for at least one day per week, and give it a full week without water once a month. This intermittent drying period supports the plant’s health and helps inhibit mold growth.
Ensure good air circulation by placing the plant in a well-ventilated area and avoiding overcrowded spaces. When rehydrating, always use clean, fresh water, changing it daily or every few days to prevent stagnation. Regular visual inspections can help catch early signs of mold, allowing for prompt intervention.
